e projection, iii, extending through low'n einii uneier imperedgeofimnneeri'i forward of hammer" hammer E whenever the latter is returnedto its normal position, as shown in Fig. 1, and when in this positionthe hammer-cannot be drawn back by the action of the trigger, orotherwise, until after the lever K has been forced down to release saidhammer, as shown in Fig. 2. The upper part, L, of lever K passesthrough, in this instance, a-slot in the main spring D, and is alsoprovided with two fingers, t, which straddle aguide-pin, u, fingerstiworking in a slot in the guard N. A. twoarmed spring, M, is fittedbetween the under side of the part L of lever Kanc the .inside of thehandle-frame A, to press the free endof said lever up against the hammerE, to insure the locking thereof whenever mainspring D throws it intothe position shown in Fig. 1.

From the foregoing description it will be seen that projection L mustfirst be depressed to unlock hammer E before trigger J can be drawn backto operate the hammer, and, fur-' ther, that hammer E cannot beaccidentally forced against the firing-pin, since the trigger, scar, andhammer are locked together by the action of lever K. It will be observedthat the bow part only of safety-lever K extends beyond the handle, andthis only in the seallopedlpart thereof; consequently the handle can befirmly grasped and held without liability of unlocking the hammer,while, when desired, by a slight depression of the center portion of thehand the bow part of safetylever K can be depressed in the scallop ofthe handle and the hammer unlocked. Accidental or premature firing ofthe arm is therefore well guarded against.

Inusing the arm the hollow of the hand first presses in projection L andunlocks hammer E, when the contraction of the finger draws back triggerJ and fires the arm. Lever K, being of a single piece, locks the hammerfar more effectually and securely than is the case when several parts orlevers are employed for that purpose, in connection with a movable partarranged in the handle to be pressed into unlock the hammer preparatoryto firing. Then, again, my arrangement of a lever, extending under thehammer and locking the same from its lower forward edge, causes theparts to work and wear more uniformly and securely than would be thecase if the arrangement of parts was such as to bring the strain uponthe hammer upon its upper part or above its pivot, where nearly all theother strain in operating the hammer comes. It will be understood thatlever K may be arranged somewhat diflerently, and also con struoted in asomewhat different form, and yet accomplish substantially the sameresults and practical advantagesabove set forth.

Having described my improvements in firearms, what I claim, and desireto secure by scalloped part of the handle, within which.

said lever is hinged, of slotted guard N, guidepin a, and fingers t onthe end L of lever K, said fingers straddling pin uand working in saidslot in guard N, all substantially as and for the purposes set forth.

2. In revolving fire-arms, the combination, with chamber or receiverBand handle A, of 'mainspring D, provided with a slot for the passage ofthe end L of'lever K, and hammer E, provided with a projection, s, toengage with the lug or catch 9 on the inner end oflever K L,substantially as and for the purposes set forth.

3. In revolving fire-arms, the combination, with hammer E, provided witha circular forwardly-projecting part for the rear curved part of thefiring-pin to rest and slide upon, and an upward projection, c, forstriking the firing-pin, of firing-pin F, fitted to rest upon theforward curved part of' the hammer, and provided with slot f, to receiveping to limit its motion, and spring G, for retracting the firing-pin,all substantially as described.

IVER JOHNSON.
